Term Use in this Manual
port-number
priority
Refers to the type of power prioritization where, within a priority class, a
PoE module assigns the highest priority to the lowest-numbered port in the
module, the second-highest priority to the second lowest-numbered port
in the module, and so on. Note that power priority rules apply only if PoE
provisioning on the module becomes oversubscribed.
priority class Refers to the type of power prioritization that uses Low (the default), High,
and Critical priority assignments to determine which groups of ports will
receive power. Note that power priority rules apply only if PoE provisioning
becomes oversubscribed.
PSE Power-Sourcing Equipment. A PSE provides power to IEEE 802.3af-
compliant or IEEE 802.3at-compliant PDs directly connected to the ports
on the module. The PoE module is an endpoint PSE.
